This has got to be one of the worst explanations. No following at all, tried it on a problem 4 different times following the forumla and such and it sucked.
Determine the volume of glacial acetic acid to prepare 500 ml of a 0.020 M acetic acid solution (glacial acetic acid; strength 99.8%, density 1.05 g/ml, MW 60.05 g/mole).
1. is pH scales is strictly btw 0 and 14? if not, why? 2. what is CSTR? is this heterogenous? is this concentration depends on location? 3. is steady state, mass can enter ot not? leave the control volume or not?
How to prepare the solutions listed below Solution 1) 25 mL 7 M sulfuric acid and the respective dilution of this solution to prepare 50 mL 2 M sulfuric acid in deionised water. Sulfuric acid Mw = 98.079 g mol-1 Sulfuric acid density = 1.84 g mL-1 Sulfuric acid purity = 98% Solution 2) 100 mL 0.02M potassium permanganate potassium permanganate Mw = 158.03 g mol-1 potassium permanganate purity = 99%
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. From the stock solution (0.020 M), pipet 4.00 mL and dilute to 100.00 mL. From the diluted solution, pipet 0.00, 1.00, 1.50, 2.00, 2.50, 5.00 and 7.50 mL aliquots into 100 mL volumetric flasks. Dilute to mark. Determine the concentration of each standard solution and tabulate.
MATLAB The acidity of solutions is generally measured in terms of pH. The pH of a solution is defined as theconcentration of hydronium ions. Create a table of conversions from concentration of hydronium ionto pH, spaced logarithmically from 0.001 to 0.1 mol/liter with 10 values. Assuming that you havenamed the concentration of hydronium ions H_conc, the syntax for calculating the negative of thelogarithm of the concentration (and thus the pH) is:pH = -log10 (H_conc)
In which situation(s) is it necessary to use a volumetric flask for maximum accuracy? to prepare a 0.150M solution of sodium chloride to measure ~25mL of water to prepare 0.1M HCI from 36-38% HCI a and c all of the above (Please type answer no write by hend)
It is known that acid content has a major effect on theflavor of vinegars, but most cheaper vinegars are diluted similarly to 5% acidity Wt./vol. % is equivalent to gsolute per 100mL solution (so 5% is equivalent to 5 g acid/100 mL solution). a.) First, calculate the approximate molar concentration of acetic acid in the 5% wt./vol vinegar. b.) Next, calculate the expected molarity of acetic acid in the solution upon dilution by a factor of 5. Thank you!
